NOTE: as per above case with VSAO, AAO has been merged into phenoscape-ext and is no longer under development.

−

As a long term goal, AAO and XAO will be aligned, XAO terms will cross reference their AAO parents, and these ontologies will be regularly synchronized. However, because AAO development is not scheduled for the first year (whereas XAO will be adding many new non-skeletal terms), an initial synchronization at the beginning of year 1 will take place, followed by cloning AAO from XAO at the beginning of year 2. Specifically, AAO terms applicable to Xenopus will be added to XAO and given an AAO xref. If AAO xrefs VSAO, then the VSAO ID should be used preferentially over the AAO ID. Relationships for xrefed terms will be the same as those in AAO. AAO terms not applicable to Xenopus won't be added or cross-referenced in XAO. In Year 1, XAO will continue to add new terms whereas AAO development will be frozen. In Year 2, AAO will be cloned out from XAO, with AAO xrefs converted into primary AAO IDs and new AAO identifiers created for terms added to XAO in year 1. The non-Xenopus AAO terms that weren't added to XAO will then be added to the newly cloned AAO. XAO will retain xrefs to AAO terms.

Revision as of 14:35, 25 September 2012

The Phenoscape project is coordinating the development and integration of multispecies and single species anatomy ontologies for vertebrates, with taxonomic focus on teleosts, zebrafish, amphibians, Xenopus, amniotes, and mouse. These ontologies are publicly available and being used and extended by the community (view the list). Where possible, we are also reusing external ontologies (e.g., PATO) from the broader biological community for the greatest interoperability across data types. The development of these ontologies follows OBO Foundry principles as much as possible, including reuse of ontology terms (by import or MIREOT) as the preferred mechanism for using shared terms. These anatomy ontologies are available from the OBO CVS-based version-control system, from which they are regularly loaded into the NCBO BioPortal where they can be readily browsed, searched, and visualized. The ontologies are also available for download as .obo files from OBO Foundry and can also be viewed using the OBO-Edit desktop or Protege software.

The existing model organism databases are largely hardcoded to reference identifiers for their own ontologies (e.g., MGI database reads MA term identifiers). In the long term, we will be exploring how to import terms into these ontologies. In the interim, the existing MOD vertebrate ontologies will continue to link to external terms using a cross-referencing strategy to external ontology identifiers (see [1])

New personnel training topics for building and using ontologies are posted here.

In the past we have held regular project anatomy ontology conference calls to discuss development with the curators of these ontologies. The limb/fin branch was the focus of ontology development in year 1 across the various ontologies described below. Currently, we coordinate our development calls with the phenotype RCN vertebrate working group monthly calls. Information about these calls is sent to the obo-anatomy, phenotype-rcn vertebrate google group, and the phenoscape project listserves. These calls are open to everyone and call in info and notes from these calls is available here: Vertebrate Working Group Wiki Page

In addition, the phenoscape curators have been meeting twice weekly to have joint ontology editing sessions. Please let us know if you would like to join us, Melissa Haendel has been coordinating these sessions (haendel@ohsu.edu).

Anatomy Ontologies

Phenoscape-ext

Phenoscape-ext contains the TAO, AAO, and VSAO combined with Uberon. We are currently in the process of reconciling the issues that arose during this merge, so you may see some messiness for a bit. This ontology will be used by phenoscape for annotation of evolutionary characters. Phenoscape-ext is our first foray into working directly in OWL.

Ontology update requests can be made on the Uberon term request tracker:
[2]

Further information about Uberon and the Phenoscape-ext merge is available here:
[4]

Vertebrate Skeletal Anatomy Ontology (VSAO)

VSAO contains terms representing structures in the skeletal system of vertebrates. It references terms from the Common Anatomy Reference Ontology (CARO), Gene Ontology (GO) Biological Process, Cell Ontology (CL), and the Phenotype and Trait Ontology (PATO). VSAO can be downloaded at the OBO Foundry and browsed at BioPortal.

Note that VSAO as released represents the outcome of the skeletal anatomy workshop held at NESCent [6] and corresponding paper due out in PlosOne.
NOTE: VSAO development moving forward has been merged into the above Phenoscape-ext ontology described above.

VSAO will be expanded to include terms in the skeletal system that are shared by two or more multispecies vertebrate ontologies. These shared terms will be imported into the multispecies ontologies. For example, ‘femur’, a term applicable to AAO and AMAO, will be added to phenoscape-ext. Shared terms that already exist in multispecies ontologies will be obsoleted, given a "replaced_by" relationship to the relevant phenoscape-ext term, and the shared term subsequently imported into the ontology. Terms shared by a multispecies ontology and its corresponding single-species ontology (e.g., AAO and XAO) would also ideally be imported from the multispecies ontology into the single species ontology (or rather, a single ontology for that taxonomic group could be used). However, because MODs currently cannot import terms, shared terms will instead be duplicated in single species ontologies and cross-referenced to the term in the external ontology. For example, because XAO and AAO both contain ‘radio-ulna’, the term XAO term will cross-reference the AAO or phenoscape-ext ID for radio-ulna.

New skeletal terms for the limb/fin and cranial skeleton have and will continue to be added based on work done at the Phenotype RCN Vertebrate Working Group meeting in Boulder, CO (June 1-3, 2011) and from ongoing work here: [7]

Amphibian Anatomy Ontology (AAO)

AAO is a multispecies ontology for amphibian anatomy. Download AAO from the OBO Foundry and browse at BioPortal

Source edit directory available here. The current version (April 2012) includes terms merged from the Xenopus Anatomy Ontology and updates from David Blackburn and Wasila Dahdul.

NOTE: as per above case with VSAO, AAO has been merged into phenoscape-ext and is no longer under development.

Development

Cross references to VSAO skeletal terms will be added

Teleost Anatomy Ontology (TAO)

TAO is a multi-species ontology for teleost fishes that was initialized with terms from the Zebrafish Anatomical Ontology (ZFA). The development of the TAO currently focuses on the skeletal system because it varies significantly across fishes, is well-preserved in fossil specimens, and it is often the focus of morphologically-based evolutionary studies in ichthyology. The development of the TAO is described in Dahdul et al. (2010). Download TAO from the OBO Foundry and browse at BioPortal.

Edit version is kept internally at ZFIN, but a prerelease edit version is available at [8]

Development

ZFA terms are cross referenced to TAO terms, and these cross references will be maintained and updated as needed. In addition, cross references to VSAO skeletal terms and uberon terms will be added.

Taxonomy Ontologies

Teleost Taxonomy Ontology (TTO)

Phenotypes are associated with species using a taxonomy ontology, the Teleost Taxonomy Ontology (TTO) derived from the Catalog of Fishes (see also the representation on BioPortal, which can be navigated on-line). The TTO is updated in concert with Catalog of Fishes updates. Changes to the TTO relative to the latest version generated from a dump from the Catalog of Fishes are documented TTO_Changes.

Amphibian Taxonomy Ontology (ATO)

The ATO is derived from the AmphibiaWeb list, which provides both taxonomy and some synonyms from ITIS and the IUCN redlist.

Vertebrate Taxonomy Ontology (VTO)

The Vertebrate Taxonomy Ontology includes the TTO, ATO, as well as a new Amniote Taxonomy Ontology. An initial release, including TTO and ATO, but using pan-vertebrate resources (see below) rather than a separate AmTO was made in May 2011. This taxonomy covers vertebrates and was built by starting with the NCBI taxonomy for vertebrates and splicing in TTO (except hagfish), ATO, and the IOC taxonomy of living birds. Synonyms from ITIS and Catalog of Life were attached if the primary name matched a name in the existing taxonomy. Subspecies names were added to their parent species as synonyms (not subclasses). The taxonomy is currently in the OBO format used for TTO and ATO, which includes the use of the Taxonomic Rank Vocabulary to tag taxa with specified rank.

Other Taxonomic Resources

Amniotes

Birds The IOC checklist provides a current taxonomy and common names, but no taxonomic synonyms.

Mammals Wilson and Reader (1993) is the standard, but the available electronic version of their taxonomy is IP encumbered.

Fossil Taxa

Paleobiology Database This covers all groups represented in the fossil record - we have implemented a way to incorporate bulk taxonomy downloads in the VTO. We are still somewhat uncertain about how hierarchies are (dynamically) built in this resource.

Taxonomic (hierarchy) Resources

NCBI This was used to fill in the gaps (non-avian amniotes) in the current proposed VTO. This provides taxonomy for GenBank submissions (including fossil taxa), but does not claim to be an authoritative source (and generally doesn't cover taxa that have not been submitted). It does provide some taxonomic synonyms as well.

ITIS Has some vetting by area experts, but coverage is not complete (nor uncontroversial).

Catalogue of Life Claimed to incorporate all of ITIS plus Species2000. Updated quarterly.

Nomenclature Resources

These can provide links to additional synonyms and resources (e.g., TTO uses fishbase to provide common names and links to their pages). Taxonomic synonyms are particularly useful as aids to data curation, but common names can assist users in browsing the website. Taxonomic resources (above) can be used as sources of names as well.

Fishbase - their taxonomy is close to TTO (both based on Catalog of Fishes), but TTO uses it strictly as a name resource.

Taxonomic Rank Vocabulary

During 2010, we released a separate Taxonomic Rank Vocabulary (TAXRANK), and removed all rank terms (e.g., family, genus, etc.) from the taxa within the TTO. Taxa in the TTO specify their ranks as property values via the metadata relation has_rank, but the object of the has_rank links is contained in the TAXRANK vocabulary.

Developing TAXRANK as a vocabulary, rather than an ontology (e.g., by defining an ordering relation between ranks) should facilitate its reuse in other taxonomic ontologies. Developing a cross-authority (e.g., ICZN, ICBN, etc.) ontology of ranks may be possible, but there does not appear to be a compelling need for such an ontology. The TAXRANK vocabulary can be browsed at Bioportal.
